Abstract: The present invention discloses a method, device, storage medium, and medical system for generating a restoration dental model. Among them, the method comprises: obtaining the restoration type of the tooth to be restored, wherein the restoration type includes at least one of the following: tooth implant type, crown restoration type, and inlay restoration type; determining the key points of the tooth to be restored based on the restoration type, where the key points of the tooth to be restored are used to represent the characteristics of the tooth to be restored; determining the restoration dental model based on the restoration type and the key points of the tooth to be restored. The present invention solves the technical problem of low efficiency of making restoration dental models artificially in related technologies.

Abstract: A custom bleaching tray or device with trench and material pocket/reservoir is disclosed. The device comprises a trench to avoid leakage of bleaching material onto the gingiva and a reservoir to precisely hold the bleaching material on the surface of the tooth. A method for forming a 3D-printed custom bleaching tray may include: providing or accessing teeth scan data associated with a patent's mouth; generating a digital model of the patient's mouth based on the teeth scan data, including manipulating the teeth scan data to form: a trench between one or more teeth and a gingiva region of the teeth scan data, and a bleaching material reservoir on a surface of each of the one or more teeth of the teeth scan data; and 3D-printing, based on the digital model, a 3D-printed bleaching tray. A thermoforming process may be applied to the 3D-printed bleaching tray.

Abstract: An adjustable oral appliance for treating sleep apnea in a user. The oral appliance includes a first appliance frame and a second appliance frame. The first appliance frame includes a first tooth tray formed integrally with the first appliance frame to engage with user's upper teeth when worn, and the second appliance frame includes a second tooth tray formed integrally with the second appliance frame to engage with the user's lower teeth when worn. The first and second appliance frames include interlocking connectors to adjust the relative position of the second frame with respect to the first frame to set the user's upper and lower jaws in proper position, to move and raise the user's tongue, and to open the user's airway to avoid sleep apnea.

Abstract: A protective oral appliance for protecting the teeth and jaws of a user from injuries during physical activity or sports. The oral appliance includes an upper mouthpiece coupled to a lower mouthpiece, and holes passing through the upper mouthpiece and/or through the lower mouthpiece to allow air to pass through the upper and/or lower mouthpieces and into the user's mouth. The oral appliance also may include an open airway positioned between the upper and lower mouthpieces.

Abstract: An orthodontic bracket and bracket support system, and its method of manufacture and use is provided. The system includes a bracket assembly including one or more bracket members to be bonded to a patient’s teeth, a placement guide assembly including one or more placement members to properly position the bracket members for the bonding procedure, and a support assembly to support the bracket assembly and/or the placement guide assembly during manufacture and use. The bracket assembly, the placement guide assembly, and the support assembly are formed together and in combination using stereolithography three-dimensional (3D) printing.
